If you know the password, login and run this: UPDATE er SET authentication_string=PASSWORD('my-new-password') WHERE USER='root' Īlternatively, you can use the following: sudo mysql_secure_installation Note that if you are using mysql-server-5.7 you can not use the easier dpkg-reconfigure method shown above. If you are not sure which mysql-server version is installed you can try: dpkg -get-selections | grep mysql-server If you are on 10.04: sudo dpkg-reconfigure mysql-server-5.1 The official and easy way to reset the root password on an ubuntu server. Set / Change / Reset the MySQL root password on Ubuntu Linux.sudo killall -9 mysqld and then start normal daemon: sudo service mysql start Replace YOURNEWPASSWORD with your new password:ĪLTER USER IDENTIFIED BY 'YOURNEWPASSWORD' Īs noted in comments by you might need to kill the temporary password-less mysql process that you started, i.e.Login to MySQL as root: mysql -u root mysql.Start the mysqld configuration: sudo mysqld -skip-grant-tables &.( In some cases, if /var/run/mysqld doesn't exist, you have to create it at first: sudo mkdir -v /var/run/mysqld & sudo chown mysql /var/run/mysqld.Stop the MySQL Server: sudo /etc/init.d/mysql stop.Enter the following lines in your terminal. But that comes with its own risks, so it's not ideal.Set / change / reset the MySQL root password on Ubuntu Linux. If course, if you have root privileges, you can reset the user's password (and change their host if necessary) to enable you to log in to do this. you know a user's password - and you are on a host you are permitted to log in from) - then you can change their password with: mysqladmin password -u Otherwise, the next argument is taken as the password. Omitting the password value should be done only if password is the final command on the mysqladmin command line. In this case, mysqladmin prompts for the password value, which enables you to avoid specifying the password on the command line. In MySQL 5.7, the new password can be omitted following the password command. ![]() Thus, the next time you invoke mysqladmin (or any other client program) using the same account, you will need to specify the new password. This changes the password to new_password for the account that you use with mysqladmin for connecting to the server. (It's no more than can be seen by anyone with access to the er table.)Īs Federico Sierra points out in the comments, you can use mysqladmin password command to change the password for any user you can log in as.įormerly the password had to be supplied on the command line, but as of 5.7, if the password is omitted it prompts for one. So it is only the password hash that is ever seen on the console/MySQL history. This can then be assigned directly to a user in MySQL: SET PASSWORD FOR = '*94BDCE.' Return '*' + hashlib.sha1( hashlib.sha1(p).digest() ).hexdigest().upper() Using MySQL code on the console defeats the purpose, but here's a fairly simple Python script that prompts for a password and generates a MySQL-compatible password string from it. The password-hashing algorithm is fairly simple, and can be replicated in other programmling languages.Īccording to, in MySQL 4.1 and up, the PASSWORD function takes the (binary) SHA1 of the password string, twice, then returns that as a hex string preceded by an asterisk.įor example, in SQL: > SELECT PASSWORD('test'), SHA1(UNHEX(SHA1('test')))
